【 摘 要 】

With the expansion of China's power system and the advancement of the power market, more and more extensive attentions have been paid on the issue of equipment utilization. The number of distribution equipment accounts for a large proportion, but the utilization of equipment is limited by many factors and distribution utilization is rather low. However, the PV penetration in distribution networks has been increasing in recent years, which changes the way distribution system operates. Therefore, it is necessary to study the distribution equipment utilization considering the PV connection. This paper summarizes the impact factors of the utilization and analyzes the impact of PV on the distribution equipment utilization. An evaluation index system for the utilization is proposed with the consideration of PV connection, which includes electric utilization indices, quantity utilization indices, life-cycle utilization indices, system-coordination indices. In addition, a typical distribution system is established analyzed to explore the impact of PV capacity and location on utilization. And the effect of several technical strategies for utilization improvement is compared and analyzed to guide the actual work of the distribution network.
